ROTARY ENGINE.

Application filed December 6, 1913.

T0 aZZ whom it may concern Be it known that I, EDWARD NEAL BATY, a citizen of the United States, and a resident of Des Moines, in the county of Folk and State of Iowa, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and exact description.

My invention has for its object to provide a rotary engine having means for opening and closing valves in a cylinder as a piston rotates therein, steam being supplied to the cylinder through one end of the piston shaft and the piston and the steam being exhausted through a port in the other end of the piston shaft. The valves may be operated either by a disk with cams which engage rollers connected with the valves or if desired the valves may be operated by pistons disposed in auxiliary cylinders having ports connected with the main cylinder to permit the passage of the steam to the pistons in the auxiliary cylinders for operating the valves at the proper time.

Still other objects of the invention will appear in the following description in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which- Figure 1 is a sectional view on the line 11 of Fig. 3; Fig. 2 is a sectional view on the line 22 of Fig 3; Fig. 3 is a sectional view on the line 33 of Fig. 2; Fig. 1 is a fragmentary sectional View showing the face of the rotary piston; Fig. 5 is a sectional view on the line 55 of Fig. 1.

By referring to the drawings it will be seen that a cylinder 10 is mounted on standards 11 supported on a base 12, this cylinder having inwardly disposed bosses 13 with bearings 14: and 15, in which the shaft sections 16 and 17 are journaled. Disposed between the bosses 13 and mounted on the shaft sections 16 and 17 there is a piston 18, this piston 13 having a hub 19 which closely fits the shaft sections 16 and 17, the piston 18 having a cam like-portion 20 which extends substantially to the inner wall 21 of the cylinder 10. The shaft sections 16 and 17 are hollow as shown in Fig. 3 of the drawings, and connected with the passage 22 in the shaft section 17, there is a port 23 in the piston 18 which extends through the face 24 of the piston. The steam is fed to Specification of Letters Patent.

the cylinder 10 through this passage 22 and the port In the hub 19 of the piston 18 there is an exhaust port 25, this exhaust port 25 leading to the passage 26 in the shaft section 16. Disposed around the piston hub 19 for a distance there is a resilient apron 2? for engagement by the inner ends 28 of the valves 32, this resilient apron 27 extending laterally beyond the sides of the hub 19 and against the bosses 13 on the cylinder heads for preventing leakage between the piston and the cylinder heads. At the sides of the face 2% of the cam like portion 20 of the piston 18 there are resilient aprons 29 for engaging the heads of the cylinders 10, and at the extreme outer portion of the face 2% there is secured to the cam like member 20 of the piston 18, a r silient apron 30 for engaging the inner circular wall of the cylinder 10, the resilient aprons 29 and 30 being provided for preventing any leakage. ln the heads of the cylinder 10 there are guide-ways 31 in which the valves 32 are adapted to move. These valves 32 extend through openings 33 in the cylinder 10 for moving in guide-ways 3%, formed in members 35 integral with the cylinder 10. Secured to the valves 32 there are rods 36 which pass through openings 37 in packing members 38 secured in openings in the members 35. The outer terminals 39 of the rods 36 are disposed in recesses 10 in brackets 41, and secured to the terminals 39 there are pins 42- which are disposed in orifices in the brackets 41 and which are provided with heads 14 at the outer sides of the brackets -11. Around the pins 42 there are disposed springs 45 for holding the inner ends 28 of the valves 32 against the resilient apron 27 when the valves 32 are moved inwardly. There are radially disposed guide-ways 46 in the head l? of the cylinder 10, and in these guideways d6 there are disposed guide-members 18, these guide-members 18 being secured for moving the brackets ll.

Mounted on the guide-members 48 there are rollers 19 for engagement by the cam rims 50 and 51 which extend from the inner side of the cam disk 52 which is secured for rotating with the shaft section 17. As will be seen by referring to Fig. 1 of the drawings, the cam rim 50 has two terminals 53 and 54, the cam rim 5O curving around the shaft section 17 and from its terminal 54, approaching the shaft section 17 for a dis tance, the cam rim extending slightly away from the shaft section 17 at its terminal 53. Nevertheless, the terminal 53 is much nearer the shaft section 17 than is the terminal 5%, the terminal 53 extending slightly away from the shaft section 17 to free the rollers 49 for engagement by the terminal 55 of the cam rim 51, the cam rim 51 curving from its terminal 55 around and away from the shaft section 17, but with its other terminal 56 bent slightly in the direction of the shaft section 17 to free the rollers 19 for engagement by the terminal 54 of the cam rim 50.

The steam enters the main cylinder 10 through the passage 22 of the port 23, the steam abutting against one of the valves 32 to rotate the piston 18. With the rotation of the piston 18, the valves 32 are moved by the engagement of the rollers 49 with the cam rims 50 and 51 so that the valves 32 will not interfere with the rotation of the piston while they still afford an abutment for the steam, the valves 32 being closed behind the piston 18 and being opened in front of the piston in a manner readily understood.

In Fig. 3 I show the shaft section 17 j ournaled in a bearing 57 in which there is a throttle having a rod 58 operated by the lever 59, the bearings 57 with the throttle, being supported on the standards 60. Packing nuts 61 are mounted on the shaft sections 16 and 17 and mesh in threaded orifices in the heads of the main cylinder 10 adjacent the bosses 13.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a rotary engine, a cylinder having sides with inwardly disposed bosses, and bearings in the bosses, shaft members journaled in the bearings and having inlet and exhaust passages, a piston disposed within the cylinder and mounted on the shaft members, aprons on the piston, the aprons being disposed adjacent the shaft members and engaging the bosses, and inlet and exhaust ports in the piston communicating with the passages, and an abutment in the cylinder against which the fluid, passing through the inlet port, may act.

2. In a rotary engine, a cylinder having sides with inwardly disposed bosses and bearings in the bosses, shaft members journaled in the bearings, a piston disposed within the cylinder and mounted on the shaft members, aprons on the piston disposed adjacent the shaft members and engaging the bosses.

In a rotary engine, a cylinder having bearings, a shaft journaled in the bearings, a piston disposed in the cylinder and secured to the shaft, a valve in the cylinder, a disk on the shaft, two rims on the disk, curved around opposite sides of the shaft and with the terminals of the companion rims adjacent each other, the terminals of one of the rims being disposed nearer the shaft than the terminals of the other rim, and means for moving the valve operable by the rims.

1. In a rotary engine, a cylinder, a piston rotatably mounted in the cylinder, a valve movably disposed in the cylinder, a rotatable disk, two rims on the disk curved around opposite sides of the shaft, the terminal of one of the rims being disposed nearer the shaft than an adjacent terminal of the companion rim and means for engagement by the rims for operating the valve.

5. In a rotary engine, a cylinder having an opening, a piston rotatably mounted in the cylinder, a valve movably disposed in the cylinder, a rod secured to the piston and disposed through the opening, a bracket having a recess and an orifice at the inner end of the recess, the outer end of the rod being disposed in the recess, a pin on the said end of the rod disposed in the orifice, a spring between the said end of the rod and the bracket at the inner end of the'recess and means for moving the bracket relatively to the cylinder with the rotation of the piston.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
